Even if a property is currently heated by natural gas, propane, above ground oil tank or current underground tank, it is important to know what other types of oil storage have previously existed. In most cases, homes in Westchester and Putnam have been heated by oil at one point since being built. This is especially true in houses built prior to 1970 (or in rural areas). Although newer houses have also relied on oil for heating purposes. In some cases, the current owners don’t even know whether a tank exists. For example, A house built in the 1920s most likely used coal for heat then oil and then natural gas. Home from the ’30s-’80s may have had heating oil than natural gas or electric.

Ground Penetrating Radar (GPR) is one of the most accurate tools used in determining if underground heating oil tanks exist at a property. Another technology is Electromagnetic Detection (ED). Barrier Contracting uses both of these technologies to identify and locate any previous and in use underground heating oil tanks or associated piping
– Ground Penetrating Radar uses radio signals to determine the characteristics of what lays underground. These signals can identify tanks, piping and various other materials beneath the surface without excavation.
– Electromagnetic Detection involves connecting a transmitter to induce radio frequency to old oil lines and using a handheld device to trace and follow them. This technology can help determine if an underground oil tank exists or has existed.
